Unitary Package Unit

Definition

A unitary package unit is a system for conditioning air, housed in an outdoor package unit similar to a rooftop unit, but with supply and return ductwork passing horizontally through an outside wall.

Purpose

Unitary package units are used to provide heating, cooling, and ventilation in buildings, typically where rooftop units are not feasible. They offer a compact, all-in-one solution for managing indoor air quality and temperature control.

Examples of Use

• Retail Stores: Installing unitary package units to provide efficient heating and cooling without the need for extensive ductwork modifications.
• Small Office Buildings: Using unitary package units to manage indoor climate, offering an easy installation and maintenance solution.
• Schools: Applying unitary package units in school buildings where rooftop space is limited or unavailable.

Related Terms

• Rooftop Unit (RTU): An HVAC unit installed on the roof of a building, providing heating, cooling, and ventilation.
• HVAC System: Heating, Ventilation, and Air Conditioning system used to control the indoor environment.
• Split System: An HVAC system with separate indoor and outdoor units, connected by refrigerant piping.

Notes

Unitary package units are favored for their simplicity and ease of installation. They are often used in applications where space constraints or building design prevent the use of traditional rooftop units.
